RESUMO
Aim: Internal disc displacement of the temporomandibular joint (TMJ) is identified by an anomaly between the condylar-disc assembly, which, in many cases, may lead to discomfort and malfunction of the chewing function. The study's objective was to assess the effects of four distinct treatment approaches on temporomandibular disorder cases with anterior disc displacements focusing on their chewing efficiency. Materials and Methods: One hundred participants suffering from reducible TMJ disc displacement were selected for enrollment in the study. Subjects were divided equally into four groups: group I patients were treated with behavioral therapy; group II patients were treated with low-level laser therapy (LLLT); group III patients were treated with anterior repositioning splints; and group IV patients were treated with flat plane splints. Chewing efficiency was assessed utilizing the fractional sieving method and a synthetic food substitute was created using silicon impression material. The statistical analysis encompassed comparisons of chewing efficiency between groups and between baseline and posttreatment within each group, employing analysis of variance (ANOVA) and paired t tests, respectively. Results: Using the paired t test, a significant difference in chewing efficiency values as expressed by the median particle size was observed between the baseline and 6-month values in all groups (P < 0.05), except for group I where no significant change was noted over the 6 months (P > 0.05). The one-way ANOVA test revealed a statistically significant difference among groups following therapies (P Ë 0.05). The post hoc Tukey test was employed for pairwise comparisons and revealed statistically significant variances in the main values of chewing efficiency among all groups at a 95% confidence level (P Ë 0.05). Conclusion: The study's results suggest that occlusal splints and LLLT are more effective in improving chewing efficiency than behavioral interventions.
RESUMO
Aims and Objectives: The study was carried out to evaluate the efficacy of four conservative therapeutic modalities on the mandibular range of motion (MRM) in subjects with anterior disc displacement with reduction (ADDwR) of the temporomandibular joint (TMJ). Materials and Methods: One hundred patients (64 women and 36 men) were selected, and randomly distributed into four groups. Group I: Subjects receiving behavioral therapy (BT). Group II: Subjects receiving low-level laser therapy (LLLT). Group III: Subjects receiving maxillary anterior repositioning splint (MARS). Group IV: Subjects receiving stabilization splint (SS). The MRM was evaluated for each patient before treatment and after 6 months. Paired t test and one-way analysis of variance (ANOVA) tests were used for statistical analysis followed by a post hoc Tukey test (P ≤ 0.05). Results: All groups showed significant improvement in MRM after 6 months of treatment (P ≤ 0.05) except for BT. There was a significant improvement for SS and MARS on the different movements of MRM, more than for LLLT and BT (P ≤ 0.05). Conclusion: The MARS and the SS are effective in increasing the MRM for patients with ADDwR.
RESUMO
Objective: was to evaluate the effect of four conservative treatment modalities on the pain level of patients with temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDwR). Material and methods:100 subjects (64 females and 36 males) were selected, divided into four groups, 25 patients of each. Subjects of Group I have been treated with behavioral therapy. Subjects of Group II had been treated with Photobiomodulation therapy (PBMT). Subjects of Group III had been treated by anterior repositioning splint (ARS). Subjects of Group IV had been treated by a stabilization splint. The pain was evaluated by visual analog score (VAS) from 0 to 10. Statistical analysis was done using one-way ANOVA test for comparison between groups. Within each group, a comparison between baseline and after treatment was done using paired t-test (p<0.05). Results: There was a statistical difference between the pain scores of the different groups after treatment (p≤0.05). Also, there were statistical differences between all groups (p≤0.05) except that between group II and group III (pË0.05). Conclusion: The use of stabilization splint and ARS are effective non-invasive methods for reducing the pain level in the treatment of TMJ ADDwR cases.(AU)
Objetivo: avaliar o efeito de quatro modalidades de tratamento conservador no nível de dor de pacientes com deslocamento anterior do disco articular com redução. Material e Métodos: foram selecionados 100 indivíduos(64 mulheres e 36 homens), divididos em quatro grupos, 25 pacientes cada. Os indivíduos do Grupo I foram tratados com terapia comportamental. Os indivíduos do Grupo II foram tratados com terapia de fotobiomodulação. Os indivíduos do Grupo III foram tratados com placa de reposicionamento anterior. Os indivíduos do Grupo IV foram tratados com uma placa de estabilização. A dor foi avaliada pelo escala visual analógica (EVA) de 0 a 10. A análise estatística foi feita usando o teste ANOVA de uma via para comparação entre os grupos. Dentro de cada grupo, uma comparação entre a linha de base e após o tratamento foi feita usando o teste t pareado (p <0,05). Resultados: Houve diferença estatística entre os escores de dor dos diferentes grupos após o tratamento (p ≤ 0,05). Além disso, houve diferenças estatísticas entre todos os grupos (p ≤0,05), exceto entre o grupo II e o grupo III (pË0,05). Conclusão: O uso de placa de estabilização e reposicionadora anterior são métodos não invasivos eficazes para reduzir o nível de dor no tratamento de casos de deslocamento anterior de disco articular sem redução.(AU)
